The more I think about the Saturday start idea, the more I like it. You could have started Berrios and a AAA guy last Saturday, and pushed everyone else back a day, meaning Gibson would get a start against Houston instead of Stewart. Or, perhaps better, start a AAA guy Saturday and use Perez out of the pen. Gives you more flexibility than just adding Romero to the pen for the day (Perez could come in earlier and/or pitch longer if necessary), and it lets you keep everyone else on the same schedule, just with Perez starting last night in Houston instead of Stewart.
